Abstract

To provide a network monitoring system extracting the performance measurement data while eliminating the performance measurement data that is not effective for improvement of the network performance on the basis of a predetermined extraction condition and presenting the extraction result to the operator. The network monitoring system includes extraction condition presenting means for presenting a predetermined extraction condition indicating a relationship between performance measurement data of each device configuring the network and a status of a device to be eliminated upon extracting said performance measurement data; and performance measurement data extracting means for eliminating the performance measurement data that is measured under a status of the device to be eliminated on the basis of an extraction condition indicated by said extraction condition presenting means and extracting the performance measurement data that is effective for improvement of the network performance.

Claims

1. A network monitoring system, comprising;

extraction condition presenting means for presenting a predetermined extraction condition indicating a relationship between performance measurement data of each device configuring the network and a status of a device to be eliminated upon extracting said performance measurement data; and

performance measurement data extracting means for eliminating the performance measurement data that is measured under a status of the device to be eliminated on the basis of an extraction condition indicated by said extraction condition presenting means and extracting the performance measurement data that is effective for improvement of the network performance;

wherein said network monitoring system provides performance measurement data that is effective for improvement of the network performance to an operator monitoring the network;

2. A network monitoring system for monitoring a performance of said network on the basis of the performance measurement data and status notification data that are transmitted from each device configuring said network, comprising a monitor terminal of an operator who monitors a network and a network monitoring device that is connected to said network;

wherein said network monitoring device comprises;

data communication processing means enabling the communication with each device configuring said network and communication with said monitor terminal of the operator;

performance measuring database for storing the performance measurement data of each device that is received via said data communication processing means;

status notification database for storing the status notification data of each device that is received via said data communication processing means;

a table for indicating a predetermined extraction condition; and

extraction and aggregate processing means for extracting the performance measurement data from said performance measurement database on the basis of a predetermined extraction condition indicated on said table with reference to said status notification database, performing the aggregate processing of the extracted performance measurement data, and transmitting the extracted performance measurement data and the aggregate processing data to said monitor terminal via said data communication processing means; and

said predetermined extraction condition indicates a relationship between said performance measurement data and the status of the device to be eliminated upon extraction.

3. The network monitoring system according to claim 2,

wherein said predetermined extraction condition is presented on said monitor terminal and can be set or changed by the operator;

the extraction condition that is set or changed by the operator is transmitted to said network monitoring device from said monitoring terminal via said data communication processing means; and

this extraction condition is stored in said table.

4. The network monitoring system according to claim 2,

wherein said aggregate processing includes temporal change of the extracted performance measurement data;

said data communication processing means transmits the temporal change of said performance measurement data and the status of the corresponding device to said monitoring device; and

said monitoring device presents the transmitted temporal change of said performance measurement data and the transmitted status of the corresponding device to the operator.

5. The network monitoring system according to claim 4,

wherein said aggregate processing includes the aggregate data including at least one of total, average, the maximum value, and the minimum value of said extracted performance measurement data;

said data communication processing means transmits said aggregate data to said monitoring device in addition to the temporal change of the performance measurement data and the status of the corresponding data; and

said monitoring device presents the temporal change of the performance measurement data, the status of the corresponding device, and the aggregate which are transmitted, to the operator.
